–Michael Steele’s woes atop the RNC are being compounded, not helped, by a handful of high-profile resignations, including chief of staff Ken McKay. Rather than looking like he’s getting his house in order, the departures inevitably lead to a series of stories citing the recent risque spending flap that, despite no evidence of his involvement, further damage the chairman’s image.

–President Obama is announcing changes to U.S. nuclear strategy, in many ways the first major post-Cold War shift. Conditions for use have been narrowed and tied to treaty status, and reaction time has been extended. Marc Ambinder explains.
